These are used in various ceilings. The E fire escape room has ceiling tiles which contain no asbestos (per the label for the tiles). The other ceiling tiles also contain no asbestos per Charles McKinnon but this needs verification. If they do contain asbestos one may keep it from flaking off by painting it with Incapsulant or Spray & Seal-it but there's a catch. The sealer itself may someday peel off and take some off some asbestos with it, resulting in a worse problem. The tiles may be tested to determine the % asbestos (if any). It's important to keep rooms with asbestos tile well vacuumed to avoid any possible accumulation of dangerous asbestos dust.
In the sanctuary, pews are stained. Applying stain to worn spots doesn't work since wood doesn't absorb it well (was a sealer used ?). So use Minwax Polyshield for touchup since it doesn't need to be absorbed by the wood to color. Used walnut color on pew ends by main aisle, but need a more redish color for foyer.
Throop Hall (wood dance floor only) 34' x 60' = 2,040 sq-ft. Original hardwood flooring is 25/32" (about 3/4" = 24/32") thick, 2 1/4" wide. Stage is oak but hall was said to be maple? Wear layer is over 3/8" of which about 3/16" has been sanded off in spots. Don't let floor finishers sand it much since once the wear layer is gone it will need to be replaced (expensive). A sealer only seals the pores and does not completely stop wear. Duraseal (by Minwax) is one but policy in 1991 was to apply a sealer intended for vinyl flooring every month or so. In 1992 used Acrylic finish. American Hardwood Floors claims that water-based varnishes do not hold up well as compared to polyurethane. Same claim made by Advanced Floor Service in 1996. But Fletco claims that their "Diamond" finish (water based) for floors (a special type of Diamond finish) is equal or better to polyurethane in wear resistance.
Was refinished in 2000? by Shaul's hardwood Floors, 310-550-1998 or 818-788-6292. Likely used water-based polyurethane. It doesn't yellow with age and dries fast in a few hours (compared to 8 hr for oil based polyurethane). It's carried by most paint stores. Made by Minwax, Spar, Valspar, Zar, Benjamin-Moore. 2004: sells for $38/gal at Charm Colors (Benjamin-M) $51/gal ICI (Zar)
For cleaning Bona Chemi is said to be good to use for wood (if finish is worn thru).
